* PLATFORM-SPRING SPECIFICATION forming part of Letters Patent No.317,095, dated May 5, 1885.

Application filed February 12, 1885. (No model.)

To all whom it may concern: I

Be it known that I, WILLIAM CRAGO, a citizen of the United States, residing at Oarbondale, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Platform- Springs; and I do declare the following to be a full, clear, and exact description of the inthe forward springs and running-gear embodying my invention.

My invention relates to carriages and wagons.

The object of my improvement consists in combining, with a platform-spring wagon, a pole or shaft attachment, whereby the said attachment may be made at the forward end of the springs on the fore axle, and at the same time having the draft direct from the axle.

The invention for this purpose consists in the following construction'and arrangement of the springs and the pole and thill connections, all of which will be first fully described, and the points of novelty then indicated in the claims.

Referring to the drawings, A represents the forward axle. B represents a clip bolted tiereon to the mid-length of the axle, and is provided with the pivotal bearing for the perch or reach 0. The pivotal bolt D connects the clip 13 and perch O. Y

E represents four cushion side springs secured to the front'and rear axle, respectively.

F represents four transversely-arranged half springs, which pass in the line of the length of the axles and connect with the ends of the cushion-springs E, as clearly shown in the drawings. A set of rectangularly-arranged platform springs are disposed under each axle, there being four springs in each set. The springs F are much longer than the side springs, E, the latter being intended to form acushion for the transverse springs. The clipconnections between the ends of the connecting-springs are formed in the usual and wellknown manner.

The connections for the coupling of the pole or thills to the wagon are made in a novel Gris a casting or forging of the general 6C shape shown in Fig. 2. It is designed not only totake the place of the usual connecting device at the forward end of the side springs, E, 1

on the forward axle, but also provides for the attachment of the pole or thills and the pivoted draft-link H, which connects the clips G to the axle A.

a b represent the holes through which the bolt-connections pass in order to secure the forwardends of the springs E to the ends of :1 has a rearwardly-extending arm, in the extremity of which the link H is pivoted by the the front transverse spring, F. The clip G bolt J. J

c are the holes which receive the thill or pole i p couplings for their attachment.

The arrangement of the clip oted link H admits of the springs being depressed without interfering with the draft action of the wagon. abled to use a shorter pole or shafts than is possible where they are attached directly to the H At, the same time I obtain a direct draft 7 axle. from the axle.

Having described my invention,what I claim as new, and desire to secure by LettersPatent of the United States, isl p 1.

In a spring-wagon provided with forward and rear side cushionsprings and transverse springs connecting'the same, the combination of clips having rearwardly-projecting" arms and connected to the forward ends of the front side springs, connections for the pole or thills,located in thefront ends of the'clips, and links pivoted at one end to the rearwardlyprojecting arms of the clips and at the other to the axle, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
